Specification of Letters Patent.

Patented April 9, 1907.

Application filed July 16, 1905. Serial No. 269,839.

To all whom it may concern:

Be it known that I, FRED M. HUNTooN, a citizen of the United States, residing at Riverside, in the county of Riverside and building without having the water touch the walk or building. I accomplish this object by means of the sprinkler described herein and illustrated in the accompanying drawings, in which Figure 1 is a side elevationof the preferred form of my improved sprinkler. Fig. 2 isa plan of the same.

In the drawings the body 3 of my sprinkler is preferably a hollow globe andis provided 3 hold the body in a vertical position.

with an attachment 4, by means of 'whicha hose 18 connected to the-sprinkler. A spear 5, attached to the body, provides means to A removable screw-cap v6 provides means by which dirt or other impurities which may en ter the center of the body may be cleaned out. The screw-cap is removed, and the'wa ter being turned on will quickly wash dirt or other impurities from within the body. When it is desired to have a sprinklerthat will sprinkle a square area of lawn or ground, the upper or top surface of the globe is perforated by perforations preferably arranged in rows, as shown. In making'these rows the outermost rows are fixed on lines that form arcs of a circle. The outer orend perforations 7, 8, 9, and 10 of -the outermost rows are placed equidistant from'each' other and dis.- tant from the horizontal circumferential line of the globe one-eighth of the circumference thereof. The perforations 11, 12, 13, and 14 are respectively equidistant from the outer or end perforations and'are at a point distant from t e topmost point or apex 15- ofthe lobe equal to. one-sixteenth of the circumerence of the globe. The perforations within the outer rows arealso preferably on the arc of a clrcle, but not necessarily so. When it is desired to sprinkle an area of lawn in the shape of a-parallelogram, the outer rows of perforations are'all ,on the arc of-a circle; but

those on opposite sides will be respectively nearer to the apex and fartherawayfrom the apex of the globe, depending upon the required length and widthof the parallelogram. It will be understood that the apex of the globe is the central-point directly above the spear, which is inserted into the ground to hold the globe in a vertical position. It will also be understood that it is only necessary that the upper half of the sprinkler should be semispherical; but I prefer to have the whole sprinkler in the form of a globe and that the two halves should be solderedtogether; but,

if desired, they may be screwed together, in which case the cleaning-cap 6 could be omitted.

Having described my invention, what I claim as n ew, and desire to secure by Letters ing equidistant om each-other and distantfrom the horizontal or base line of the hemispherical portion the one-eighth of the circumference of the lobe of which the u per portion forms onealf, the central pe orations of said outer rows'being equidistant from the end erforations and one-half closer to the apex o the top than the end perforations.

2. As an article of manufacture, 'a sprinkler comprising a hollow body having a convex or' curved outer surface, the center or a ex of such surface having perforations .t erein, in the general form of a rectangular figure, thecorners of which extend opposite each other on' the op osite sides of t e surface so that the jets 0 water issuing from the perforations-extend ap roximately all the .way from horizontal at t e extreme points to vertical at the apex of the dome or convex surface. I

witness that I claim the foregoing I I have hereunto subscribed my name this 24th day of June, 1905.
